Application filed October 8, 1920. Serial No. 415,469.

T 0 all whom it may concern:

Be it known that I, LAWRENCE C. Soon), a citizen of the UnitedStates,residing at Buffalo, in the county of Erie and State of New York, haveinvented new and useful Improvements in Radiators, of which thefollowing is a full, clear, concise, and exact description, referencebeing had to the accompanying drawing, forming a part of thisspecification.

My invention relates to improvements in radiators and particularlythattype of radiator adapted for use with steam or hot Water in heating airwhich is mechanically forced through the radiators.

One of the objects of my invention is to provide a radiator of thischaracter which shall be compact in size without sacrificing radiatingsurface, which shall be light in weight, and which may be readily andeasily manufactured.

Another object of my invention is to rovide a radiator of this typewhich s all split the air up into fine streams so that all of the airwill come intointimate contact with the heat radiating surface andbecome thoroughly heated thereby.

Still another object of my invention is to provide means whereby airwhich is in the fluid circulating coils of the radiator before theheating fluid is admitted thereto, ma be readily expelled and airpockets in the uid circulating coils be prevented.

For the purpose of disclosi my invention I have illustrated one em imentthereof in the accompanying drawings in which,

Fig. 1 is a side elevation of two sections of my radiator unitsconnected together,

Fig. 2 is an end elevation thereof, parts of same being shown insection,

'Fig. 3 is a sectional view taken on the line e 3 of Fig. 2,

Fig. 4 is a detail sectional view showing the manner of mounting theradiator fins on the circulatin coils,

Fig. 5 is a etail perspective view of one of the radiating fins, and

Fig. 6 is a side elevation of a modified form of header.

In the embodiment illustrated the radiators are constructed in unitswhich units are adapted to be connected together, as many units beingconnected as desired. In the construction of the unit, I providepreferably, rectangular end plates 1 and 2. These end plates areprovided with equally spaced apart openings of any number desired. Inthe structure illustrated I have s'howntwo rows of openings, one rowconsisting of twelve openings and the other consisting of elevenopenings, the openings of the shorter row are staggered with relation tothe openings of the longer row. Extending between the headers I providecirculating pipes 3 which are adapted to be fitted within the openingsof the top and bottom plates and are swaged or turned over at 4 tosecurely hold them in position.

Secured on the circulating pipes 3 are radiatin fins 5. These finspreferably consist of at sheet metal rectangular plates having theiredges turned up to form spacer members 6. In assembling the structure asshown the plates are arranged on the pipes in groups, each plate beingadapted to embrace seven pipes, and to form the unit illustrated in thedrawing three plates are arranged side b side in horizontal alignment,and serve to ivide the apparatus into three separate vertical sections.These plates are arran ed one on top of the other and are suitab yspaced apart by turned up spacer flanges 6. In order that the plates mayproperly pass the pipes opposite their edges they are notched as at 7.After the fins have been assembled on the pipes, the unit thus formed isgiven abath of galvanizing solder which intimately unites the fin andpipes together, protects the parts against rust, and insures positivemetal contact for the transmission of heat to the fins. The insidesurfaces of the circulating pipes are also coated with the galvanizingsolder, which protects those surfaces from rust due to the corrosiveaction of the condensed steam or hot water within the pipes.

Secured over the top and bottom plates are rectangular manifolds orheaders 8 and 9. These headers comprise rectangular boxes havingoutwardly extending flanges 10 by which they are securely bolted to thetop and bottom plates 1 and 2. The headers are closed on one side by anarcuate wall 11 extending diagonally from one end of the header to theother to form a chamber diminishing in size from end to end. The largeend of the header is provided with an internally threaded opening intowhich is adapted to be connected the supply or dis charge pipe. Due tothe construction ofthe header the size of the header contracts away fromthe supply openings thereof and toward the closed end so that when steamis size of the header most remote from the ad mission point of the steamis substantially the same as that at the admission point there isatendency of part of the steam to flow with the greater velocity andpressure through the circulating pipes connected at the ends of theheader so that air pockets are formed in the intermediate circulatingpipes preventing the admission of steam equally to all of thecirculating pipes.

By making the boxes rectangular in shape and the side walls tlre sameheight through the entire box I provide means whereby the sections maybestacked one on top of the other without difliculty. In place, however,of providing rectangular boxes that portion of the walls which serves nofunction as a conduit may be eliminated and suitable spacer membersformed on top of the header to form supports as illustrated in Figure 6.

I have found by experience that the heat of the heating fluid passingthrough the pipes is conducted by the radiating fins to the outermostsurface thereof and that, due to the construction and arrangement ofthese fins in connection with the circulating pipes, the air is split upas it is driven through the heater in fine streams so that all of theair comes intomost intimate contact with heating radiating surfaces andthe air is thereby thoroughly warmed.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is- 1. An apparatus of the character describedcomprising a manifold, a plurality of tubes communicating therewith, and

members arranged in superposed relation' and embracing a group of saidtubes; flanges at the opposite ends of said members adapted to engagewith the surface of the adjacent member whereby to form side walls and aplurality of horizontal passages intermediate said tubes, substantiallyas specified.

2. An apparatus of the character described comprising a manifold, aplurality of tubes communicating therewith, and a plurality of series ofmembers arranged in superposed relation, and the members of each seriesembracing a group of said tubes; flanges at the opposite ends of saidmembers adapted to engage with the surface of the adjacent memberwhereby to form side walls and a plurality of horizontal assagesintermediate said tubes, substantia 1y. as specified.

3. An apparatus of the character described comprising a manifold, aplurality of parallel tubes engaging therewith, and a plurality ofseries of horizontally arranged members disposed in superposed relation,and the members of each series embracing a group of said tubes; flangesat the opposite ends of said members adapted to engage with the surfaceof the adjacent members whereby to form unbroken side walls and aplurality of horizontal passages intermediate said tubes, substantiallyas specified.

4. An apparatus of the character described comprising a pair ofmanifolds, a plurality of parallel tubes secured at their opposite endsto said manifolds and communicating therewith, and a plurality of seriesof horizontally disposed flat members arranged in superposed relationserving to divide the apparatus into a plurality of vertical separatedsections, said superposed members of each series each embracing a groupof said tubes, and flanges extending at right angles from the oppositeends of said flat members adapted to engage with the surface of theadjacent flat members whereby to form unbroken side walls and aplurality of horizontal passages intermediate said tubes, substantiallyas specified.

In witness whereof, I have hereunto subscribed my name.
